					<p>Models hold the essential data of a diagram, describing the basic entities and their properties and relationships
						without specifying the appearance and behavior of the Nodes and Links and Groups that represent them visually.
					Models tend to hold only relatively simple data, making them easy to persist by serialization as JSON or XML formatted text.</p>
					<p>Models hold simple data objects, not <a href="Part.html">Part</a>s such as <a href="Node.html">Node</a>s or <a href="Link.html">Link</a>s.
						Node data is normally represented in a <a href="Diagram.html">Diagram</a> by instances of <a href="Node.html">Node</a>,
						but they could be represented by simple <a href="Part.html">Part</a>s or by <a href="Group.html">Group</a>s.
						A Diagram constructs Parts for its <a href="Diagram.html#model">Diagram.model</a>&#39;s data by copying templates.
						Templates are <a href="Panel.html">Panel</a>s of <a href="GraphObject.html">GraphObject</a>s that get some property values from the model data,
						accessible via the <a href="Panel.html#data">Panel.data</a> property, using data <a href="Binding.html">Binding</a>.
					See <a href="../../intro/usingModels.html">Using Models</a> and <a href="../../intro/dataBinding.html">Data Binding</a> for an introduction.</p>
					<p>This Model class only supports holding an array of node data
						and interpreting properties on that data to be able to refer to them
						using unique key values.
						To support simple tree-structured graphs, use a <a href="TreeModel.html">TreeModel</a>, which inherits from this class.
					To support links and grouping, use a <a href="GraphLinksModel.html">GraphLinksModel</a>.</p>
					<p>Each node data object is assumed to have a unique key value.
						The <a href="Model.html#nodeKeyProperty">nodeKeyProperty</a> property names the property on the node data whose value
						is the unique key for that node data object.
						The default value for this property is &quot;key&quot;.
						You should not have a TwoWay data binding on the node key property,
					because that might cause the property value to be set to a duplicate key value.</p>
					<p>The key values must be either strings or numbers or undefined.
						If the key is undefined, or if there are duplicate key values,
						the model will automatically try to assign a new unique key value.
						Caution: if your keys are numbers, do not try to use string representations of those numbers as keys.
						Conversely, if your keys are strings that happen to have number syntax, do not try to use those number values.
					Sometimes JavaScript will automatically convert from string to number or vice-versa, but sometimes it won&#39;t.</p>
					<p>For example, one can define a graph consisting of just two nodes:</p>
					<pre><code class="hljs js"> model.nodeDataArray = [
   { <span class="hljs-attr">key</span>: <span class="hljs-string">"Alpha"</span> },
   { <span class="hljs-attr">key</span>: <span class="hljs-string">"Beta"</span> }
 ];</code></pre>
					<p>This model cannot detect the modification of the <a href="Model.html#nodeDataArray">nodeDataArray</a> array
						or the modification of any node data object.
						If you want to add or remove node data from the <a href="Model.html#nodeDataArray">nodeDataArray</a>,
					call the <a href="Model.html#addNodeData">addNodeData</a> or <a href="Model.html#removeNodeData">removeNodeData</a> methods.</p>
					<p>If you want to modify a node data object, it depends on whether the property you want to change
						is a structural property that the model needs to know about, or whether it is a property
					that is only used for data binding or other application-specific purposes.</p>
					<p>For the former case, call the appropriate method, such as
						<a href="Model.html#setKeyForNodeData">setKeyForNodeData</a>, <a href="Model.html#setCategoryForNodeData">setCategoryForNodeData</a>,
						<a href="GraphLinksModel.html#setToKeyForLinkData">GraphLinksModel.setToKeyForLinkData</a>, or <a href="GraphLinksModel.html#setGroupKeyForNodeData">GraphLinksModel.setGroupKeyForNodeData</a>.
					These methods have names that start with &quot;set&quot;, &quot;add&quot;, &quot;insert&quot;, or &quot;remove&quot;.</p>
					<p>For the latter case, when setting an application-specific property, typically for data binding,
					and to support undo/redo, call <a href="Model.html#setDataProperty">setDataProperty</a>.</p>
					<p>The <a href="Model.html#copyNodeData">copyNodeData</a> method can be called to make a shallow copy of a node data object.
						However, if some of those property values are Arrays that want not to be shared but to be copied,
						you can set <a href="Model.html#copiesArrays">copiesArrays</a> to true.  This is typically very useful when dealing
						with data bound item arrays.
						Furthermore if the items in those copied Arrays are in fact Objects that need to be copied,
						you can also set <a href="Model.html#copiesArrayObjects">copiesArrayObjects</a> to true, causing a copied Array to refer to
					newly shallow-copied objects of the original array.</p>
					<p>Each model raises <a href="ChangedEvent.html">ChangedEvent</a>s that you can follow by registering a listener via <a href="Model.html#addChangedListener">addChangedListener</a>.
					Read more at the Introduction page: <a href="../../intro/changedEvents.html">Changed Events</a>.</p>
					<p>Each model comes with its own <a href="UndoManager.html">UndoManager</a> that is initially not enabled.
						You will need to set <a href="UndoManager.html#isEnabled">UndoManager.isEnabled</a> to true in order for the
					UndoManager to record model changes and for your users to perform undo and redo.</p>
					<p>You can temporarily turn off the recording of changes by setting <a href="Model.html#skipsUndoManager">skipsUndoManager</a> to true.
						A number of places within the system do that routinely in order to avoid recording temporary changes,
						so be sure to remember the original value beforehand and restore it afterwards.
					Note that in a <a href="ChangedEvent.html">ChangedEvent</a> listener you may want to ignore events that happen when <a href="Model.html#skipsUndoManager">skipsUndoManager</a> is true.</p>
					<p>One normally saves a diagram by just saving its model.
						If you can use JSON-formatted text, this is easy to do -- just call <a href="Model.html#toJson">toJson</a>
						to get the string representation of the model, and save that string.
						Load the diagram by replacing the <a href="Diagram.html#model">Diagram.model</a> with one created by calling
					the static function <a href="Model.html#static-fromJson">Model.fromJson</a>:</p>
					<pre><code class="hljs js">  myDiagram.model = go.Model.fromJson(loadedString);</code></pre>
					<p>Note that JSON and other textual data formats cannot faithfully store all JavaScript functions.
						<a href="Model.html#toJson">toJson</a> and <a href="Model.html#static-fromJson">Model.fromJson</a> do not try to save and load functional property values.
						You should arrange that all such functions, including event handlers, are established by your app.
						<a href="Model.html#toJson">toJson</a> and <a href="Model.html#static-fromJson">Model.fromJson</a> also cannot handle circular references; any sharing of
						references will be lost too.
					They also skip properties that are not enumerable, those whose names start with an underscore, and those whose values are undefined.</p>
					<p>Note that models also do not store the templates used by diagrams,
						nor any transient or temporary parts such as <a href="Adornment.html">Adornment</a>s, nor any tools,
						nor any <a href="UndoManager.html">UndoManager</a> state, nor any event listeners.
					These objects and all other properties of diagrams must be established by your app.</p>
					<p>You can add any number of properties to the <a href="Model.html#modelData">modelData</a> object, which is serialized and deserialized
						into JSON just like any other model data for nodes or links.
						However <a href="Model.html#modelData">modelData</a> is associated with the model as a whole and does not depend on the existence
					of any node data or link data.</p>
					<p>It is also easy to save the changes that were recorded in the most recent transaction.
						Call <a href="Model.html#toIncrementalJson">toIncrementalJson</a> to generate a JSON-format string that holds the current state of modified data
						plus the keys of inserted or removed data.
						That method requires as an argument a <a href="ChangedEvent.html">ChangedEvent</a> that represents a transaction that completed or
					an undo or a redo that just finished.</p>
					<p>It is also possible to use such &quot;incremental&quot; JSON to modify an existing model.
						Call <a href="Model.html#applyIncrementalJson">applyIncrementalJson</a>, giving it a string generated by <a href="Model.html#toIncrementalJson">toIncrementalJson</a>,
						to modify this model by making all of the changes recorded in the JSON text.
					Note how this method is a regular instance method, whereas <a href="Model.html#static-fromJson">Model.fromJson</a> is a static function.</p>

								<p>Make a copy of a node data object.
									This uses the value of <a href="Model.html#copyNodeDataFunction">copyNodeDataFunction</a> to actually perform the copy, unless that property is null.
								When it is null the default behavior is to just make a shallow copy of the JavaScript Object.</p>
								<p>However when <a href="Model.html#copiesArrays">copiesArrays</a> is true, this will make a copy of property values that are JavaScript Arrays.
									This is useful when you do not want the Arrays to be shared between the node data objects.
									Note that if you want to copy some property values that are Arrays but not other properties that are Arrays,
								you cannot use <a href="Model.html#copiesArrays">copiesArrays</a> but must implement your own <a href="Model.html#copyNodeDataFunction">copyNodeDataFunction</a>.</p>
								<p>In addition when <a href="Model.html#copiesArrayObjects">copiesArrayObjects</a> is true, if items in the Array being copied are JavaScript Objects,
									those objects are copied, recursively.
									This is useful when the items in copied Arrays are themselves objects that need to be copied.
									Note that if you want to share references to some but not all of the objects in copied Arrays you cannot use

								<p>Produce a JSON-format string representing the changes in the most recent <a href="Transaction.html">Transaction</a>.
									This writes out JSON for a model, but recording only changes in the given Transaction,
									with the addition of the &quot;incremental&quot; property to mark it as different from a complete model.
									Instead of the &quot;nodeDataArray&quot; property (and &quot;linkDataArray&quot; property for <a href="GraphLinksModel.html">GraphLinksModel</a>s),
								this will have &quot;inserted...&quot;, &quot;modified...&quot;, and &quot;removed...&quot; properties that are non-empty Arrays.</p>
								<p>The &quot;modifiedNodeData&quot; Array holds JavaScript objects.
									The &quot;insertedNodeKeys&quot; and &quot;removedNodeKeys&quot; Arrays hold keys (numbers or strings) of data,
									not whole objects, that have been added and/or deleted.
								The &quot;modelData&quot; property holds the <a href="Model.html#modelData">Model.modelData</a> object, if it was modified.</p>
								<p>Note that it is entirely plausible for the same object be in or referenced by all three Arrays,
								because a single <a href="Transaction.html">Transaction</a> can include adding a node, modifying it, and removing it.</p>
								<p>The purpose of this method is to make it easier to send incremental changes to the server/database,
									instead of sending the whole model.
								Whereas it has always been easy to perform &quot;batch&quot; updates or &quot;file saves&quot;:</p>
								<pre><code class="hljs js">  myDiagram.addModelChangedListener(<span class="hljs-function"><span class="hljs-keyword">function</span>(<span class="hljs-params">e</span>) </span>{

      <span class="hljs-comment">// save the whole model upon each transaction completion or undo/redo</span>
      ... send to server/database ...
    }
  });</code></pre>
								<p>You can now easily send &quot;incremental&quot; updates:</p>
								<pre><code class="hljs js">  myDiagram.addModelChangedListener(<span class="hljs-function"><span class="hljs-keyword">function</span>(<span class="hljs-params">e</span>) </span>{
    <span class="hljs-keyword">if</span> (e.isTransactionFinished) {
      <span class="hljs-keyword">var</span> json = e.model.toIncrementalJson(e);
      <span class="hljs-comment">// record each Transaction as a JSON-format string</span>
      ... send to server/database ...
    }
  });</code></pre>
								<p>Note that these incremental changes include the results of undo and redo operations.
									Also, when you might call <a href="Model.html#applyIncrementalJson">applyIncrementalJson</a>, you will need to disable your Changed listener,
								so that it does not send spurious changes to your database during the process of apply incremental changes from the database.</p>
								<p>For <a href="GraphLinksModel.html">GraphLinksModel</a>s, this method requires that <a href="GraphLinksModel.html#linkKeyProperty">GraphLinksModel.linkKeyProperty</a> is not an empty string.
									The incremental JSON for GraphLinksModels will include &quot;modifiedLinkData&quot;, &quot;insertedLinkKeys&quot;, and &quot;removedLinkKeys&quot;
								properties that are non-empty Arrays.</p>
								<p>The same restrictions on data property names and data property values applies to this method as it does to <a href="Model.html#toJson">toJson</a>.</p>

								<p>There must not be any circular references within the model data.

								<p>Most object classes cannot be serialized into JSON without special knowledge and processing at both ends.
									The <a href="Model.html#toJson">toJson</a> and <a href="Model.html#static-fromJson">Model.fromJson</a> methods automatically do such processing for numbers that are NaN

									<a href="Brush.html">Brush</a> (but not for brush patterns), and for <a href="Geometry.html">Geometry</a>.
									However, we recommend that you use Binding converters (static functions named &quot;parse&quot; and &quot;stringify&quot;)
									to represent Points, Sizes, Rects, Margins, Spots, and Geometries as string values in your data, rather than as Objects.
								This makes the JSON text smaller and simpler and easier to read.</p>
								<p>As a special case when serializing an object, if the property is named &quot;points&quot; and the
